Solar cell module

Abstract

A solar cell module comprises: a solar cell panel; a terminal box mounted to the back surface of the solar cell panel, which is one surface thereof; a frame mounted to the edges of the solar cell panel; and a metallic first cover composed of a base section for covering the back surface of the terminal box, which is one surface thereof, and of an affixation section affixed to a frame which composes the frame.

The invention claimed is: 
     
       1. A solar cell module comprising:
 a solar cell panel; 
 a terminal box having a substantially rectangular parallelepiped shape comprising a first surface, a second surface opposing the first surface, and a side surface, the first surface being attached to a surface on one side of the solar cell panel; 
 a frame that is attached to an end edge of the solar cell panel; 
 a metal cover comprising:
 a base that covers the second surface of the terminal box; and 
 a fixation unit that is fixed to the frame; and 
 
 a diode and a terminal base provided in the terminal box; 
 wherein the base has a first edge in a width direction of the base and a second edge in the width direction of the base opposite to the first edge; 
 a length of the first edge of the base in a longitudinal direction approximately perpendicular to the width direction is longer than a length of the second edge of the base in the longitudinal direction; 
 wherein the fixation unit is provided at the first edge of the base, and the fixation unit extends from the base in a direction approximately perpendicular to the width direction of the base and the longitudinal direction of the base, 
 a back surface of the solar cell panel is positioned on the first surface of the terminal box and an upper surface of a body of the frame; and 
 the terminal box is positioned such that the side surface of the terminal box is provided along and facing a side surface of the body of the frame; 
 when viewed along a direction parallel to the side surface of the terminal box, the fixation unit is positioned between the side surface of the terminal box and the side surface of the body of the frame; 
 the upper surface of the body of the frame faces the back surface of the solar cell panel, which is a surface on a side opposite to the light receiving surface; 
 the terminal box is attached on the back surface of the solar cell panel by an adhesive; 
 wherein the frame is provided on an opposite surface to a surface on which the terminal box is provided; and 
 the frame comprises;
 a flange portion extending from the end edge of the solar cell panel towards a center of the solar cell panel such that the flange portion entirely covers the terminal box when viewed from the opposite surface; and 
 a concave portion to which the solar cell panel is fitted. 
 
 
     
     
       2. The solar cell module according to  claim 1 , wherein
 the terminal box and the metal cover are attached along a longitudinal direction of the frame, 
 the solar cell module further comprises a side wall section that is provided at the second edge of the base and that covers a side surface of the terminal box. 
 
     
     
       3. The solar cell module according to  claim 1 , wherein
 the terminal box and the metal cover are attached along a longitudinal direction of the frame, 
 the fixation unit comprises a first fixation unit and a second fixation unit, the first fixation unit being provided at a first end of the base in the longitudinal direction of the base, and the second fixation unit being provided at a second end of the base in the longitudinal direction of the base. 
 
     
     
       4. The solar cell module according to  claim 1 , wherein
 the fixation unit is screwed to the frame via a toothed washer. 
 
     
     
       5. The solar cell module according to  claim 1 , wherein
 the body of the frame comprises a cavity; and 
 a corner piece is squeezed onto the cavity of the body of the frame.
